Installation
2.2 Installation Procedure
Select a location that is dry and away from extreme temperatures to mount the ME-
BMK Sense Module and DC shunt; using the supplied #8 x 3/4 screws (x4). Allow
ample room to view the LED on the Sense Module, access the screws and bolts on
the shunt; and to access the terminal block and the RJ11 port.
CAUTION: Do not mount the ME-BMK sense module in a closed battery
compartment or in an area
where water
or any other liquid can enter the
ME-BMK sense module and cause shorting or corrosion. The internal circuit
board is conformal coated to help prevent corrosion, but this failure is not
covered by the warranty.
Info: Shunts should be mounted in an area where freely circulating air is
available. For continuous operation, it is recommended that shunts are
not used at more than 2/3 of their rated current. If this is not possible,
adequate forced ventilation should be provided to keep the shunt operat-
ing temperature below 60°C.
CAUTION: Before beginning the installation, ensure all AC power is dis-
connected from the inverter; and all negative and positive battery cables
are disconnected from the battery bank.
2.2.1 DC Cable connections
1. Using an appropriate sized cable, wire the inverter’s DC negative terminal to
the DC Shunt (load side).
Info: For the ME-BMK to monitor all load currents, all DC loads - including
the inverter - must be connected to the load side of the shunt.
2. Wire the other side of the DC Shunt (battery side) to the battery negative terminal.
Connect
cables/hardware to the shunt exactly as shown in
figure 2-2.
3. Using an appropriate sized cable, wire the inverter’s DC positive terminal to the
load side of an appropriate DC disconnect/overcurrent protection device (i.e. DC
Circuit Breaker or DC disconnect and fuse).
4. Open the DC circuit breaker (or remove the fuse) and wire its other side to the
positive terminal of the battery bank.
